[On] September 21, Heydrich [Himmler’s chief assistant] forwarded to the Army High Command a copy of his initial “housecleaning” plans. As a first step the Jews were to be herded into the cities (where it would be easy to round them up for liquidation). “The final solution,” he declared, would take some time to achieve and must be kept “strictly secret,” but no general who read the confidential memorandum could have doubted that the “final solution” was extermination. Within two years, when it came time to carry it out, it would become one of the most sinister code names bandied about by high German officials to cover one of the most hideous Nazi crimes of the war.

Heydrich was head of the Reichssicherheithauptamt [RSHA], an amalgam of the SS SD,and the Sicherpolizei [Security Police], consisting of the Kriminalpolizei-Criminal Police, and the Geheime Staatz Polizei-Gestapo. Interestingly, he had no authority over the Ordnungspolizei, or Order Police-the uniformed ‘regular’ police commanded by Kurt Daleuge], nor over the Concentration Camps or their guard detachments which were under the Inspectorate for Concentration Camps [first under Theodor Eicke, and later, Richard Gluecks].

As to Shirer’s claim that Heydrich was telling the Army in 1939 about the “Final Solution”, that's a crock.
